The sunflower plant
植物 zhí wù is dicotyledonous. This
means the plants 植物 zhí wù
has two seed leaves. The bright yellow petals attract pollinating
insects 昆虫 kūn
chóng. The small almost invisible stamen and stigma mean
that the sunflower 向日葵 xiàng
rì kuí plant is not pollinated by wind.

What is interesting about the
sunflower 向日葵 xiàng
rì kuí is that it is a composite flower
head (pseudanthium). That means
that the "flower" 花 huā
we see is actually a combination of a few flowers. "Florets" is
the name given to the small flowers that make up the composite flower
head. Interestingly, the growth or development of the
florets demonstrate the Fibonacci
